IIVLPROVEIIIENT IN OX-BOW PIN'.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Y Be it known that I, HENRY P. JUDsoN, of Bethlehem, in the' county of Litchlield, and State of Connecticut, have invented lcertain new and useful Improvements in Orr-Bow Pins; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

.while in use, by means of the wire springs'on the sides,

constructed and attached to the centre-pin or key, in the manner herein described. I

A is part of the bow through which the pin passes. B is a cross-head, formed in one piece, of castor wrought-metal, with the pin G.

To this head are attached the side springs D D,-

which pass through the openings EE, to support them and key them in place. l

The springs D D are bent round, in the form shown in the drawings, and secured, at F, by means of the clips a a a a, which are bent ldown over the wire of the sp1-ing after it has been placed in the proper position upon the circular portion, i), of the cross-head.

At Gr the wire is bent into a loop of the proper form to ride over the sides of the bow when the pin C is pressed into the hole bored to receive it. i

The operation of myinvention is as lfollows:

When it is desired to place the pin in the bow, the point of C is placed in the hole and the pin pressed in. The parts G G Arideover the surface of the bow and separate the springs D D.

.When the bow and pin are in the position shown in the drawings, the springs close and retain the pin in its place in the bow. l y

When it is desired to remove it, a pull upon the end, B, separates the springs and withdraws the pin.
